It's a funny coincidence – or perhaps, in the mind of Rod Serling, not at all – that this episode immediately follows the episode "Third from the Sun", because they have a somewhat similar and yet entirely different twist at the end. Both episodes handle about space travel (admittedly like many other ones in the franchise) and end with a revelation about a certain location/destination that is identical, and yet the context is completely different. Quite vague, I know, but I can't possibly elaborate further without giving away essential clues. Also, the outcome of both episodes can be predicted relatively easy in case you pay close attention and if have a little bit of experience in watching Sci-Fi/horror. But that certainly doesn't mean that the end twists aren't original or intelligent; - quite the contrary. In "I Shot an Arrow into the Air" the rocket and 7-headed crew of a space mission disappears from the radar almost immediately after take-off and vanish. The crew on the ground fears they drifted off and pray they are still alive but fear the worst. Then the action cuts to the mission's crew as they crashed on a planet with nothing but sandy hills and the burning heat of the sun surrounding them. Three members of crew died instantly and another one is practically dead as well, and thus tensions regarding leadership and the consumption of the remaining water supplies promptly come to the surface. Crew member Corey emerges as the obligatory egocentric and loathsome survivalist freak and unhesitating to kill the others for a few extra drops of water. The irony of the end twist, and particularly the emotional impact it has on the last remaining survivor, is a masterful little piece of TV suspense.
